This set came in with the 75 ohms 2w resistor R4745 open on the High Voltage regulator board , causing no high voltage regulation, replaced it and explode again in seconds. found voltage low on pin3 of the regulator IC U4751, after checking voltages around, found reference voltage coming from the high voltage splitter, was too low, 42V instead of the normal 59V, replacing the high voltage splitter cure the problem.
